It seems a commonly held notion that the actual written text of Buddhadharma were only recorded well after the life of the Buddha. However, this sutta seems to indicate that was not so:
"Take a mendicant who says: ‘Reverend, I have heard and learned this in the presence of the Buddha: this is the teaching, this is the training, this is the Teacher’s instruction.’ You should neither approve nor dismiss that mendicant’s statement. Instead, you should carefully memorize those words and phrases, then check if they’re included in the discourses and found in the texts on monastic training. If they’re not included in the discourses and found in the texts on monastic training, you should draw the conclusion: ‘Clearly this is not the word of the Blessed One, the perfected one, the fully awakened Buddha. It has been incorrectly memorized by that mendicant.’ And so you should reject it."
Isn't this prima facie evidence that contrary to this belief that actual teachings were written down and consulted during the life of the Buddha?
